Abstract

ABSTRACT
Apple peel, a nutrient-dense byproduct of apple processing, is rich in dietary fibre, polyphenols, and antioxidants but remains underutilised. This study investigated the effects of freeze-drying and osmotically pretreated freeze-drying on the quality attributes of apple peel tea.
The teas were analysed for physicochemical properties, proximate composition, vitamin content, phytochemical profiles, antioxidant capacity, and sensory attributes, and results revealed significant differences (p
